Two Indo-Persian ? daggers for I.D. and comment

[colin henshaw]

Hi

I recently acquired these two daggers, and as I have only limited knowledge of Indian weapons, would someone be able to identify and date them for me please.

The one with the silver scabbard (came with some African material), looks like it has a walrus ivory handle, whilst the other one has a bone handle.

Any information would be appreciated, thanks.
